You can use proc sgplot to create line plots in SAS.

This procedure uses the following basic syntax:

/*create dataset*/
proc sgplotdata=my_data;
    seriesx=x_variable y=y_variable;run;

The following examples show how to use this procedure to create line plots in SAS.

Example 1: Create Line Plot with One Line

Suppose we have the following dataset in SAS that shows the total sales made by a store during 10 consecutive days:

/*create dataset*/
data my_data;
    input day $ sales;
    datalines;
1 7
2 12
3 15
4 14
5 13
6 11
7 10
8 16
9 18
10 24
;
run;

/*view dataset*/
proc printdata=my_data;

We can use proc sgplot to create a line plot that displays the day on the x-axis and sales on the y-axis:

/*create line plot that displays sales by day*/
proc sgplotdata=my_data;
    series x=day y=sales;
run;

We can use the following code to modify the appearance of the chart, including the title, labels, colors, line pattern, and line thickness:

/*create custom line plot*/
title "Sales by Day";
proc sgplotdata=my_data;
    seriesx=day y=sales / lineattrs=(color=red pattern=dash thickness=4);
    xaxisdisplay=(nolabel noline noticks);
run;
title; 

Example 2: Create Line Plot with Multiple Lines

Suppose we have the following dataset in SAS that shows the total sales made by three different stores during five consecutive days:

/*create dataset*/
data my_data;
    input store $ day $ sales;
    datalines;
A 1 13
A 2 18
A 3 20
A 4 25
A 5 26
B 1 3
B 2 7
B 3 12
B 4 12
B 5 11
C 1 6
C 2 12
C 3 19
C 4 20
C 5 21
;
run;

/*view dataset*/
proc printdata=my_data;

We can use proc sgplot with the group argument to create a line plot that displays the sales made by each of the three stores:

/*create line plot that displays sales by day for each store*/
title "Sales by Day by Store";
proc sgplotdata=my_data;
    styleattrsdatacontrastcolors=(red green blue);
    seriesx=day y=sales / group=store;
run;
title;

The x-axis displays the day and the y-axis displays the sales made by the stores.

The three individual lines show the sales made by each of the three stores during each day.
